How to Make a Stereoscope

Step-by-Step Guide

1. 1

   Step 1: Note that a stereoscope consists of four parts: a backing board; a lens holder; a separator; and a connecting strip.

   Place the connecting strip so that it holds the backing board and the lens holder at the correct focusing distance of the lenses.
   
   This is known as the “focal length".
   
   Put the separator between the lenses.
   
   This is to stop your eyes from looking at the photo on the other side. , Use lenses with no more than a 2X magnification for normal-sized photographs.
   
   You can use greater magnifications for smaller pictures.
   
   You can even dismantle a cheap pair of reading glasses for the lenses if you cannot find any other source. ,,
